The Tower of Nero is the final installment of Rick Riodan’s most recent series called The Trials Of Apollo. In the last book, Apollo travels with his 12-year-old master/companion Meg, who is the daughter of Demeter. They both get jumped by an old friend of Meg’s, Lu. Lu helps them escape from the Germani, who were sent by Nero to capture them. They then get the 2nd line of Apollo’s final prophecy. It tells them to go to the place of the “7 layer dip” (Percy Jackson’s house). Turns out Percy isn’t home, and Lu, Apollo, and Meg instead just stay the night and plan to go to Camp Half-Blood in the morning. They take a ride on the Gray Sisters Taxi and make it (barely) to Camp Half-Blood. Meg went off to the Demeter cabin, Lu decided to go explain what happened to Nero, and Apollo gets a visit by Mr. D and his son, Will, before promptly collapsing.
As not to spoil the ending of this fantastic book, I’ll have to stop the review here. But, If you appreciate mythology books (or just fantasy books), I highly recommend reading this series. It is packed with many emotional moments and fun easter-eggs from his other books.
